Is 3 a factor of 315?

Here we will show you two different methods you can use to determine if 3 is a factor of 315.

The first method entails simply listing all factors of 315 and then seeing if 3 is one of them. The factors of 315 are 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, and 315. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 315?" is therefore yes.

For the second and perhaps easier method, we divide 315 by 3 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 3 is a factor of 315. If the quotient is a fractional number, then 3 is not a factor of 315.

315 divided by 3 is 105 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 315?" is yes.
